Terrible triad injury of the elbow: A PROCESS-compliant surgical case series from Eastern Morocco.

Ann Med Surg (Lond) 2022 Jun 4;78:103914. Epub 2022 Jun 4.

Department of Traumatology and Orthopedics, Mohammed VI University Hospital, Oujda, Morocco.

Introduction: The terrible triad of the elbow (TTE) is a lesion associating a dislocation of the elbow, a fracture of the radial head, and a fracture of the coronoid process, with a high potential of complication. The treatment is based on the restoration of bone lesions and external capsular ligament repair. The systematic repair of the medial collateral ligament (MCL) is still debated in the literature. The aim of this study is to evaluate the clinical and functional results of the surgical treatment in a real-world series from Easter Morocco.

Patients And Methods: This was a retrospective study of 6 cases of TTE operated by isolated external approach or combined approach (internal or anterior) of the elbow in the department of Traumatology-Orthopedics of the Mohammed VI University Hospital (Oujda Morocco), over a period of 7 years from 2013 to 2020. Radial head and coronoid process fractures were classified according to the Mason and Morrey-Regan classifications, respectively. The following clinical parameters were evaluated: Mayo Clinic Elbow Performance Score (MEPS), Quick Disabilities of the Arm, Shoulder and Hand (DASH), Visual Analog Scale (VAS), and arc of mobility in flexion-extension and prono-supination.

Results: 6 male patients treated between May 2013 and December 2020 were included. The median follow-up was 48 months. All patients had frontal and lateral standard X-ray of over and under joints, and computed tomography (CT)-scan was delivered for 5 cases. The elbow dislocation was posterolateral in five cases, and posteromedial in only one patient. Radial head fractures were classified as type I in one case, type II in two cases, and type III in three cases. Coronoid fractures were type I in three cases, type II in one case, and type III in two cases. At the last follow up, the mean MEPS, Quick DASH, and VAS was 81, 28, 0.8, respectively. The mean arc of mobility in flexion was 120° and it was deficient by 20° in extension. In addition, the mean arc of mobility in protonation was 80°, while in supination it was 75°. Regarding complications, we noticed an instability of the elbow on valgus in a single case, elbow stiffness with heterotopic ossification in a single case, ulnar nerve damage in a single case during medial collateral ligament anchoring, and elbow hygroma in one single case.

Conclusion: The surgical management of TTE can provide good and long-term functional results after restoration of the stabilization of bone structures and the lateral ligament complex, without the need to repair the medial collateral ligament.

Hair-zinc levels determination in Algerian psoriatics using Instrumental Neutron Activation Analysis (INAA).

Appl Radiat Isot 2013 Feb 14;72:177-81. Epub 2012 Nov 14.

Psoriasis is a multifactorial skin disease with an unknown etiology. Zinc has a positive impact on psoriasis. The aim of this study is to determine hair-zinc concentration in Algerian psoriatics. 58 psoriatics and 31 normal controls of both genders were selected. Hair zinc levels were determined using Instrumental Neutron Activation Analysis technique (INAA). Student's t-test and One-Way ANOVA were applied. The average zinc concentration for controls and patients were 152 ± 53 μg/g and 167 ± 52 μg/g respectively. They are not significantly different (p>0.05). Zn concentration for males and females controls and patients were 171±27 μg/g, 151±37 μg/g and 145 ± 59 μg/g, 178 ± 58 μg/g respectively. However, for females we have observed a significant difference (p<0.05).

[Retinal detachment following posterior capsulotomy using Nd:YAG laser. Retrospective study of 144 capsulotomies].

J Fr Ophtalmol 1993 ;16(2):87-94

Clinique Ophtalmologique Universitaire, Créteil.

Nd:YAG capsulotomy is currently performed after extracapsular cataract surgery and seems to increase the risk of postoperative retinal detachment. In order to evaluate the incidence of this complication in our experience, we retrospectively studied 144 patients who underwent Nd:YAG laser posterior capsulotomy with at least a six-month follow-up. Six patients out of 144 (4.16%) subsequently developed rhegmatogenous retinal detachment. The average time from extracapsular cataract surgery to YAG capsulotomy was 21 months (11 to 26 months). The average time from capsulotomy to retinal detachment was 3.6 months (1 to 8 months). In 4 out of 6 eyes, at least one risk factor for retinal detachment was present (myopia, lattice degeneration, retinal detachment in the fellow eye). Vitreous cells were observed in 4 patients after capsulotomy. In 2 patients, a prophylactic laser photocoagulation had been previously performed. These retinal detachments were not different from aphakic or pseudophakic detachment, but the examination of retinal periphery was particularly difficult because of the peripheral capsular fibrosis, hiding retinal tears in 4 eyes. Two cases of moderate proliferative vitreoretinopathy were observed. Retinal reattachment surgery was successful in all cases with one procedure. The YAG laser energy required to create a capsulotomy was less than that reported in the literature, and no relationship could be established with the total energy applied. Nd:YAG capsulotomy seems to moderately increase the risk of retinal detachment, especially in myopic patients. The mechanisms of vitreous and retinal damage after Nd:YAG capsulotomy are discussed.
